  2. 1. Experimental Design and Updating of Finite Element Models

    Author : Magnus Andersson; Lennart Ljung; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis deals with two partly related topics: model updating and actuator/sensor placement concerning finite element (FE) models of large, flexible mechanical structures.The importance of accurate dynamical FE models of mechanical structures in, e.g., aviation/aerospace applications are steadily increasing.

  4. 2. Behavioral and Structural Model Based Approaches to Discrete Diagnosis

    Author : Magnus Larsson; Lennart Ljung; Inger Klein; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The basic motivation for this thesis is the fact that things go wrong. With the growing complexity of todays engineering systems, the need has arisen for systematic approaches to failure diagnosis, i.e., fault detection and isolation. READ MORE

  5. 3. On Modeling and Diagnosis of Discrete Event Dynamic Systems

    Author : Magnus Larsson; Lennart Ljung; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The basic motivation for this thesis is the fact that things go wrong. With the growing complexity of todays engineering systems, the need has arisen for systematic approaches to failure diagnosis. In this thesis an approach for modeling and diagnosis of systems that fall in the area of discrete event dynamic systems is proposed. READ MORE

  6. 4. Initialization Methods for System Identification

    Author : Christian Lyzell; Lennart Ljung; Martin Enqvist; Magnus Jansson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System identification; Initialization methods; Regressor selection; Identifiability; Automatic control; Reglerteknik;

    Abstract : In the system identification community a popular framework for the problem of estimating a parametrized model structure given a sequence of input and output pairs is given by the prediction-error method. This method tries to find the parameters which maximize the prediction capability of the corresponding model via the minimization of some chosen cost function that depends on the prediction error.

  7. 5. Labile Verbs in English : Their Meaning, Behavior and Structure

    Author : Alan McMillion; Magnus Ljung; Nils-Lennart Johannesson; Ulf Magnusson; Stockholms universitet; []
    Keywords : HUMANIORA; HUMANITIES; labile verbs; ergative verbs; transitivity; causative; constructions; English language; Engelska språket;

    Abstract : English has many verbs that syntactically occur in both transitive and intransitive clausal patterns. A subset of such verbs are called labile verbs, and these have a causative sense when they occur in the transitive pattern and a non-causative or inchoative sense in the intransitive pattern.
